' 2 Claims This invention relates to a combination chalkboard molding strip and map display railhook' supporting member and is an improvement upon the map display rail and hook supporting mem her which is disclosed in Elmer W.'Christy Patent No. 1,930,965 granted October 17, 1933, on Display Railand Hook?- An object of thefpresent invention is to provide a new and improved combination chalkboard molding strip and map display rail hook supportmg member which may be used advantageously in conjunction with chalkboards in school rooms and like places, for retaining the upper edge portion of a chalkboard in position of use upon and against a vertical wall surface while, at the same time', providing a support for a map display rail hook, supporting member such as that which is disclosedfin the aforesaidPatent No. 1,930,965. I

Another object of the present invention is to provide a new and improved and relatively simple and inexpensive combination chalkboard molding strip and map display rail hook sup-' porting member having a unique "and pleasing design and appearance which are such that it may be 'used as a chalkboard molding strip, per se, as" and when desired, 'and'without modification or reconstruction, while; at the same time, being available for use as a map display railhook supporting member if it should be desired to use the new chalkboard molding strip for that additional purpose andfunction.

Gther objects will appear hereinafter. Fig. l is a front elevationalviewillustrating the new combinationchalkboard molding stripand map display rail hook supporting member in position of use inconjunction with a chalkboard and upon the vertical wall of a schoolroom or like-place;

Fig. 2 is an enlarged fragmentary elevational View of the construction'shownin Fig; 1;

Fig. 3 isa fragmentary vertical sectional view. on lii1e3--3 inFig.2 I Fig. 4- is a top plan view on line 4-4 in Fig. 2, partlyinsection; and- Fig. 5 is; a fragmentary enlarged sectionalview similar'to Fig. 3 but showing the mapdisplay rail hocksupporting member in the position which it assumes, when beingv introduced into and removed; from the new combination chalkboardmolding strip. and map display. rail hook slipporting member.

A preferred embodiment of the new combination. chalkboard molding, strip and map display.

rail hook supporting member is illustrated in. the drawing, wherein it-is. generally indicated at H1, and is shown as being used in conjunction.

with chalkboard I I which is-m-ounted upon the surface I2 of a vertically extending wall 13 in a school-room or like place.

The new combination chalkboard molding strip and map displayrail hook Supporting memher is formed as a one-piece unitary metal stripe suitably cast or extruded through a forming die from suitable metal such, for example; "as an aluminum alloy, and comprises a body H having an inclined upper edge 1:5 and including an upwardly extending attaching flange portion I 5 at the rear thereof. This attaching flange portion I6 is attached to the vertically extending wall {3 by means of suitable fastening elements, such as the screw l1. V t

The new combination chalkboard 1 molding strip and map display rail hook supporting member ID has a notched or indented portion 18 on its rear surface tFig. .3)' and in use this notched or indented portion 18 overlies and rests upon the top edge of the chalkboard I I. v

The new combination chalkboard molding strip and map display rail hook supporting member I also includes a vertically extending and de- I pending flange H'which, in use, extends downwardly across the face of the upper end portion of the chalkboard ll so as to retain the chalk board H firmly against the vertically extending wall [3 of a schoolroom or like placeyas shown in Fig. 3.

The new combination chalkboard molding strip and map display rail hook supporting memher also has asubstantially channel-shaped guideway 20 formed therein and extending lengthwise therethrough This guideway 20 is formed, in part, by a horizontally extending ledge 0r flange 2|, which. is arranged at the bottom thereof, and this horizontally extending ledge or flange 2| projects inwardly from a vertically extending wall 22 which projects downwardly from the body II at the front thereof, and 'forms the front wall of the substantially channel-shaped guideway 20. As shown in Fig; 3', the top of the guideway is formed by the body; M of the new combination chalkboard molding strip and map display rail hook supporting 'mem-' ber.

The channel-shaped guideway' 20 has an inlet opening or mouth 23, at the inner end thereof, for a purpose which will be described presently. A map display rail hook supporting member is generally indicated at 24 in the drawing and is of substantially the same construction as the map display rail hook supporting member-disclosed in the aforesaid Patent No.e1,930,965.,=and com- 24 has a. rightangularly extending upper end portion 3 0.

7 A substantially flat leaf spring member 21 is V mounted upon the face of the body 25 of the hook 24 and is suitably attached thereto between its ends as by means of a rivet 28. The upper end portion 29 of the flat leaf spring member 21 is normally bowed slightly outwardly'from the body of the hook 24, and this end portion 29 of the fiat leaf spring member 21 terminates slightly short of the angled end portion of the body 25 of the hook 24.

In the use of the new combination chalkboard V molding strip and map display rail hook supporting member lllthe same may be mounted in position of use, as shown, with the horizontallye'xtending edge I8 thereof disposed above and resting upon the top edge of a chalkboard l I and with the upwardly extending attaching flange I6 of the member if! attached to a vertical wall surface l3, as-by means of the screw l1, so as to retain the chalkboard H firmly thereagainst.-

' Whenso disposed, the new combination chalkboard molding strip and map display rail hook supporting member 10 not-only functions as a ohalkboardmolding strip, to -retain the upper edge portion'o'f the chalkboard H firmly against thevertical'wall surface I3, and in position of use thereon, but is also useful for supporting the map display rail hooks 24.

' The map display rail hooks 24 are adapted to support a display roll map 3| in position of'use upon the chalkboard H and to accomplish this result a pair of the map display rail hooks 24 inay be mounted in position of use in spaced relationship, as shown in Fig; 1. In order to inount the map display rail hooks 24 in position of use upon the new combination chalkboard molding stripand'map display rail hook supporting member It the hooks 24 are positioned at an; acute angle relative to the member l0 and chalkboard i'l, and the upper end portion 29 of the flat leaf spring 21 compressed slightly inwardly against the body 25 of the hook 24. The rightangularly extending upper edge portions -30 of the map display rail hooks '24 are thereupon inserted through the mouth or throat 23 into the.

channel-shaped guideway 28 whereupon the hooks '24 are manipulated relative to the substantially channel-shaped guidewayZi] and the body l4 of theoombination chalkboard molding strip and map display rail hook supporting member l0 until the rightangularly extending upper edge portion 39 rests upon the horizontally and inwardly extending ledge or shelf 2! of the member l0, and the body 25 of each hook 24extends substantially vertically and bears against the face of the chalkboard H, as shown in Fig. 3. When. so disposed the upper end portion 29 of each flat leaf spring member 21 bears against the inner edge of the ledge or shelf 21 and serves to keep the hooks 24 in proper position.

.Whenso disposed, the trunnions 32 of a roll display map 3| may be rested upon the hook portions 2:; of the hook 24, as shown in the drawing. i 4

In order to remove each hook 24 from the substantially channel-shaped guideway 20, it is merely necessary manually to press the upper and map display rail hook supporting member provides a novel dual purpose unit in that not only does it function to provide a chalkboard e molding strip for retaining the upper edge portion of the chalkboard ll firmly against the vertically extending wall surface l3, but it also serves as an efficient support for the map display rail hooks 24.

Moreover, the new combination chalkboard molding strip and map display rail hook supporting member may be used as a chalkboard molding strip, per se, independently of themap display rail hooks 24, and when so used provides an efiicient chalkboard'molding strip which is simple and efiicient in construction and has a novel and pleasing ornamental design and appearance.

' It will thus be seen from the foregoing description, considered in conjunction with the accompanying drawing, that the present invention provides a new and improved combination chalk-' board molding strip and map'display rail hook supporting member having the desirable advantages and characteristics, and accomplishing its intended objects, including those hereinbefore pointed out and others which are inherent in the invention.
